States of Matter & Types of Solids Test

Which state of matter has a definite shape and volume?

• Liquid

• Gas

• Plasma

• Solid

What characteristic best describes gases?

• They have a definite shape but no definite volume.

• They have no definite shape or volume.

• They have strong intermolecular forces.

• They can only exist at high temperatures.

Which of the following best describes plasma?

• A state of matter with weakly moving particles.

• A state of matter that behaves like a liquid and a solid.

• A high-energy state where atoms lose electrons.

• A state with definite volume but no definite shape.

Which process causes a change in matter? (Choose all that apply)

• A change in the anount of energy between the particles.

• A chemical reaction

• A change in shape and size

• None are correct

The forces that hold solid particles together in a fixed position are known as:

• Electromagnetic forces

• Intermolecular forces

• Electrostatic forces

• Gravitational forces

Which of the following is an example of an ionic solid?

• Sodium chloride (NaCl)

• Gold (Au)

• Ice (H₂O)

• Carbon dioxide (CO₂)

Molecular solids are typically held together by:

• Ionic bonds

• Metallic bonds

• Covalent bonds and intermolecular forces

• Electrostatic forces

Which characteristic is true of metallic solids?

• They are brittle.

• They conduct electricity.

• They dissolve easily in water.

• They do not have a crystalline structure.

What determines the strength of an ionic solid?

• The lattice energy

• The shape of the ions

• The size of the molecule

• The presence of intermolecular forces

Lattice energy refers to:

• The amount of energy needed to break a metallic bond.

• The energy required to separate ions in an ionic solid.

• The energy holding molecular solids together.

• The energy of moving electrons in a solid.
